1表面溶解对从不同脉石矿物中浮选分离钛铁矿的动力学参数的影响(英文)显示文摘研究表面酸溶解对钛铁矿(IL)及其常见伴生脉石矿物(包括橄榄石-辉石(Ol-Px)、透闪石-斜绿泥石(Tr-Cch)和石英)浮选动力学的影响。结果表明,通过表面溶解,钛铁矿的吸附速率常数从5.272增大到8.441 mol/(g·min),而Ol-Px、Tr-Cch和石英的吸附速率常数分别从6.332、7.309和7.774mol/(g·min)减小为5.034、6.223和7.371mol/(g·min)。二元混合矿物的浮选实验结果表明,经表面溶解后,从Ol-Px、Tr-Cch和石英中浮选钛铁矿的修正速率常数值分别从36.15、36.52和47.86min^-1增大到41.72、45.78和56.24min^-1,导致从脉石矿物中分离预处理过的钛铁矿过程的动力学选择性指数(SI)增大。ICP-MS分析证实,脉石矿物动力学参数的降低可能是由于其表面Fe^2+、Ca^2+和Mg^2+的去除,导致矿物表面缺乏足够的活性位点与捕集剂组分发生作用。接触角测量结果证实,表面溶解可防止矿物表面形成稳定的疏水层,从而可在矿物和气泡之间发生稳定的附着。一般来说,钛铁矿浮选动力学参数的提高与伴生脉石矿物中的铁含量呈负相关关系。Omid SALMANI NURI Mehdi IRANNAJAD Akbar MEHDILO 2019Transactions of Nonferrous Metals Society of China2019,29,12:10
2Comparison of one and three initial monthly intravitreal ranibizumab injection in patients with macular edema secondary to branch retinal vein occlusion显示文摘AIM: To compare three initial monthly intravitreal ranibizumab(IVR) injections followed by pro re nata(PRN) dosing with one initial monthly IVR injections followed by PRN dosing for macular edema(ME) secondary to branch retinal vein occlusion(BRVO).METHODS: Forty-two eyes of 42 patients who had IVR injections for BRVO were retrospectively studied. Eighteen eyes received 1 initial IVR injection(1+PRN group) and 24 eyes received 3 monthly IVR injections(3+PRN). At 1, 3, 6 and 12mo; spectral-domain optical coherence tomography(SD-OCT) was performed. Central macular thickness(CMT), the integrity of the external limiting membrane(ELM), the presence of subretinal fluid, cyst size, the presence of inner segment/outer segment(IS/OS) defect were determined.RESULTS: At baseline the mean CMT was 521.3±153.2 μm in the 3+PRN group while it was 438.1±162.4 μm in 1+PRN group. At the final visit, mean CMT was 278.3±87.8 μm in the 3+PRN group and 285.2±74.2 μm in the 1+PRN group(P=0.079). The changes in CMT over the entire study period were also comparable in both groups(243±160 μm in the 3+PRN group, and 152.9±175.3 μm in the 1+PRN group; P=0.090). At baseline, best-corrected visual acuity(BCVA) was 0.92±0.60 logarithm of the minimal angle of resolution(logMAR) in the 3+PRN group, while it was 0.72±0.46 logMAR in the 1+PRN group. Final BCVA was 0.42±0.55 logMAR in the 3+PRN group and 0.38±0.50 logMAR in the 1+PRN group(P=0.979). Additionally, the BCVA changes from baseline to final visit were not significantly different(-0.50±0.45 logMAR in the 3+PRN group, and-0.33±0.39 logMAR in the 1+PRN group; P=0.255).CONCLUSION: No significant differences in the anatomical or functional results are found between 3+PRN and 1+PRN regimens in the patients receiving ranibizumab for ME secondary to BRVO. Intact IS/OS and baseline BCVA are good predictor of the visual gain, while baseline CMT is a good predictor of the anatomical gain.Alper Halil Bayat Akin Cakir Seyma Gülcenur Ozturan Selim Bolükbasi Burak Erden Mustafa Nuri Elcioglu 2018International Journal of Ophthalmology(English edition)2018,11,9:6
3Mitochondrial dysfunction,oxidative stress and apoptotic induction in microglial BV-2 cells treated with sodium arsenate显示文摘The treatment of microglial BV-2 cells with sodium arsenate(As(V):0.1-400 μmol/L — 48 hr)induces a dose-dependent response.The neurotoxic effects of high concentrations of As(V)(100,200 and 400 μmol/L) are characterized by increased levels of mitochondrial complexesⅠ,Ⅱ,and Ⅳ followed by increased superoxide anion generation.Moreover,As(V) triggers an apoptotic mode of cell death,demonstrated by an apoptotic SubG1 peak,associated with an alteration of plasma membrane integrity.There is also a decrease in transmembrane mitochondrial potential and mitochondrial adenosine triphosphate ATP.It is therefore tempting to speculate that As(V) triggers mitochondrial dysfunction,which may lead to defective oxidative phosphorylation subsequently causing mitochondrial oxidative damage,which in turn induces an apoptotic mode of cell death.Wafa Kharroubi Samia Hai Ahmed Thomas Nury Pierre Andreoletti Rachid Sakly Mohamed Hammami Gerard Lizard 2017Journal of Environmental Sciences2017,29,1:5
4Imatinib response of gastrointestinal stromal tumor patients with germline mutation on KIT exon 13:A family report显示文摘Familial gastrointestinal stromal tumor(GIST) is a rare autosomal dominant disorder associated with mutations in the KIT gene in the majority of cases. Although, exon 11 appears to be the hot spot region for approximately 95% of germline mutations, pathogenic variations have also been identified in exon 8, 13 and 17. Exon 13 germline mutations are extremely rare amongst familial GISTs and seven families with a germline mutation have been reported to date. Moreover, the role of imatinib mesylate in this rare familiar settings is not completely known so far. We describe here clinical, imaging, pathological and genetic findings of a family with four affected members; grandmother, his son and two grand-sons having a germline gain-of-function mutation of KIT in exon 13 and discuss the imatinib mesylate treatment surveillance outcomes towards disease management.Gulgun Engin Serpil Eraslan Hülya Kayserili Yersu Kapran Haluk Akman Ali Akyuz Nuri Faruk Aykan 2017World Journal of Radiology2017,9,9:3
5Lung parenchymal changes in patients with ankylosing spondylitis显示文摘AIM: To assess lung parenchymal changes in ankylosing spondylitis (AS) using high resolution computed tomography (HRCT). METHODS: We included 78 AS patients whose average age was 33.87 (18-56) years with a ratio of 53 males to 25 females who were followed up for 3.88 (1-22) years on average. neumonia and tuberculosis were excluded. In a detailed examination of lung HRCT findings, we investigated the presence of parenchymal micronodules,parenchymal bands, subpleural bands, interlobular and intralobular septal thickening, irregularity of interfaces,ground glass opacity, consolidation, mosaic pattern,bronchial wall thickening, bronchial dilatation, tracheal dilatation, pleural thickening, emphysema, thoracic cage asymmetry, honeycomb appearance, structural distortion, apical fibrosis and other additional findings.RESULTS: In detailed HRCT evaluations, lung parenchymal changes were found in 46 (59%) of all patients. We found parenchymal bands in 21 (27%) cases, interlobular septal thickening in 9 (12%), emphysema in 9 (12%), apical fibrosis in 8 (10%), ground-glass opacities in 7 (9%), parenchymal micronodules in 5 (6%), irregularity in interfaces in 3 (4%), bronchial dilatation in 3 (4%), mosaic pattern in 2 (3%), pleural thickening in 2 (3%), consolidation in 1 (1%), bronchial wall thick ening in 1 (1%) and a subpleural band in 1 (1%) case. Furthermore, we detected subsegmental atelectasis in 2 patients and a cavitary lesion in 1 patient. CONCLUSION: Our study had the highest number of AS cases of all previous studies in evaluating lung paren chymal changes. The rate of lung parenchymal changes was slightly lower than that reported in recent literature.Zehra Isik Hasiloglu Nuri Havan Aylin Rezvani Mustafa Akif Sariyildiz Halil Eren Erdemli Ilhan Karacan 2012World Journal of Radiology2012,4,5:3
6Legalon-SIL downregulates HCV core and NS5A in human hepatocytes expressing full-length HCV显示文摘AIM: To determine the effect of Legalon-SIL (LS) on hepatitis C virus (HCV) core and NS5A expression and on heme oxygenase-1 (HMOX-1) and its transcriptional regulators in human hepatoma cells expressing full length HCV genotype 1b. METHODS: CON1 cells were treated with 50 μmol/L or 200 μmol/L LS. Cells were harvested after 2, 6 and 24 h. HCV RNA and protein levels were determined by quantitative real-time polymerase chain reaction and Western blotting, respectively. RESULTS: HCV RNA (core and NS5A regions) wasdecreased after 6 h with LS 200 μmol/L (P < 0.05). Both 50 and 200 μmol/L LS decreased HCV RNA levels [core region (by 55% and 88%, respectively) and NS5A region (by 62% and 87%, respectively) after 24 h compared with vehicle (dimethyl sulphoxide) control (P < 0.01). Similarly HCV core and NS5A protein were decreased (by 85%, P < 0.01 and by 65%, P < 0.05, respectively) by LS 200 μmol/L. Bach1 and HMOX-1 RNA were also downregulated by LS treatment (P < 0.01), while Nrf2 protein was increased (P < 0.05).CONCLUSION: Our results demonstrate that treatment with LS downregulates HCV core and NS5A expression in CON1 cells which express full length HCV genotype 1b, and suggests that LS may prove to be a valuable alternative or adjunctive therapy for the treatment of HCV infection.Marjan Mehrab-Mohseni Hossein Sendi Nury Steuerwald Sriparna Ghosh Laura W Schrum Herbert L Bonkovsky 2011World Journal of Gastroenterology2011,17,13:3
7Superior labrum anterior to posterior lesions of the shoulder: Diagnosis and arthroscopic management显示文摘After the improvement in arthroscopic shoulder surgery,superior labrum anterior to posterior(SLAP)tears are increasingly recognized and treated in persons with excessive overhead activities like throwers.Several potential mechanisms for the pathophysiology of superior labral tears have been proposed.The diagnosis of this condition can be possible by history,physical examination and magnetic resonance imaging combination.The treatment of type 1 SLAP tears in many cases especially in older patients is non-operative but some cases need arthroscopic intervention.The arthroscopic management of type 2 lesions in older patients can be biceps tenodesis,but young and active patients like throwers will need an arthroscopic repair.The results of arthroscopic repair in older patients are not encouraging.The purpose of this study is to perform an overview of the diagnosis of the SLAP tears and to help decision making for the surgical management.Nuri Aydin Evrim Sirin Alp Arya 2014World Journal of Orthopedics2014,5,3:2
8Red cell distribution width and nonalcoholic steatohepatitis显示文摘Red cell distribution width is a measure of deviation of the volume of red blood cells.It is a marker of anisocytosis and often used to evaluate the possible causes of anemia.Elevated red cell distribution width levels are also associated with acute and chronic inflammatory responses.In nonalcoholic steatohepatitis,inflammation is accompanied with steatosis.For assuming red cell distribution width as a marker of nonalcoholic steatohepatitis,intervening factors such as levels of inflammatory markers should also be evaluated.Yasemin Gulcan Kurt Tuncer Cayci Fevzi Nuri Aydin Mehmet Agilli 2014World Journal of Gastroenterology2014,20,43:2
9Biepicondylar fracture dislocation of the elbow joint concomitant with ulnar nerve injury显示文摘In this article, we present a case of humeral biepicondylar fracture dislocation concomitant with ulnar nerve injury in a seventeen year-old male patient. Physical examination of our patient in the emergency room revealed a painful, edematous and deformed-looking left elbow joint. Hypoesthesia of the little finger was also diagnosed on the left hand. Radiological assessment ended up with a posterior fracture dislocation of the elbow joint accompanied by intra-articular loose bodies. Open reduction-Internal fixation of the fracture dislocation and ulnar nerve exploration were performed under general anesthesia at the same session as surgical treatment of our patient. Physical therapy and rehabilitation protocol was implemented at the end of two weeks post-operatively. Union of the fracture lines, as well as the olecranon osteotomy site, was achieved at the end of four months post-operatively. Ulnar nerve function was fully restored without any sensory or motor loss. Range of motion at the elbow joint was 20-120 degrees at the latest follow-up.M Nuri Konya Ahmet Aslan Hakan Sofu Timur Y?ld?r?m 2013World Journal of Orthopedics2013,4,2:2

11Acetabular components with or without screws in total hip arthroplasty显示文摘AIM To compare the operation time, blood loss, and early outcomes of acetabular components with and without the screw.METHODS Thirty patients who underwent cementless acetabular component with or without screw and whose follow-up exceeded one year period in total hip arthroplasty were evaluated. A posterior approach was used in all surgical procedures by one experienced surgeon. Demographic data, operation time, intra-and postoperative blood loss volume, follow-up clinical score, cup migration, and osteolysis were recorded. The Kolmogorov-Smirnov test was performed for testing the normality of study data. Mann-Whitney U test was used to analyze the intergroup differences. A P-value of ≤ 0.05 was considered statistically significant.RESULTS Acetabular components were used in 16(53.3%) patients with screw and 14(46.7%) without screw. After one year of follow-up, an osteolytic lesion of 3 mm was found in only one patient in the screw group. No cup migrationwas encountered. Intra-group mean Harris hip score significantly increased, but there was no significant intergroup difference. While the mean operation time of the screw group was 121.8 min(range; 95-140), it was 102.7 min(range; 80-120) in the no-screw group, and this difference was statistically significant(P = 0.002). The mean intraoperative/postoperative, and total blood loss were 556.6 mL(range: 350-800)/423.3 mL(range: 250-600), and 983.3 mL(range: 600-1350), respectively in the screw group; and 527 mL(range: 400-700)/456 mL(range: 230-600), and 983 mL(range: 630-1250), respectively in the no-screw group. The blood loss difference between the two groups was not significant. In the screw group, the operation time was 19.1 min longer than the no-screw group, and this difference was statistically significant.CONCLUSION Acetabular components with or without screw have similar results, but the use of screw increases the operation time significantly, while not changing the blood loss volume.Murad Pepe Onur Kocadal Tamer Erener Kubilay Ceritoglu Ertugrul Aksahin Cem Nuri Aktekin 2017World Journal of Orthopedics2017,8,9:2
